[0019] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the utility model will be briefly introduced in combination with the drawings and the description of the embodiments or the prior art, and obviously, the following description of the structure of the drawings is only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained without creative labor. It needs to be explained that the description of these embodiment modes is used to help understanding the utility model, but does not constitute the limitation of the utility model.

[0020] In the dust remover structure, the cooperation of the flower plate 7 and the blowing pipe 8 is as shown in the top view effect drawing Figure 4 , the blowing pipe 8 is located above the flower plate 7, the blowing hole 801 on the blowing pipe 8 corresponds coaxially with the flower plate hole 701 on the flower plate 7, and when the compressed gas blows through the blowing hole 801 on the blowing pipe 8 as the blowing gas blowing filter element 9, the state is as shown in Figure 5 , it is necessary to ensure that the blowing hole must be located at the upper center position of the filter element outlet. For the above structure, the utility model designs a kind of installation alignment device suitable for different specifications of blowing pipe blowing hole and flower plate hole.

[0021] EMBODIMENT:

[0022] As Figure 1 , Figure 2 and Figure 3As shown, the embodiment provides a device for installing and aligning the injection hole of the injection pipe and the hole of the flower plate, which comprises a hole aligning device 1, an injection hole aligning device 2, an extension guide column 3, an adjustable nut 4 and a compressible spring 5. The sum of the spring forces of the two compressible springs 5 is greater than the gravity of the injection pipe. In actual use, for example, Figure 3 As shown, the device for installing and aligning the injection hole of the injection pipe and the hole of the flower plate can be used in two ways. The hole aligning device 1 is a hollow conical platform with a vertical central hole in the middle, and the outer diameter of the hole aligning device 1 gradually decreases from top to bottom. In this way, the hole aligning device 1 can be placed in the hole 701 of the flower plate. When placing, the upper end surface of the hole aligning device 1 is ensured to be horizontal. The middle part of the extension guide column 3 is a smooth structure matching through the vertical central hole. The lower part of the extension guide column 3 is a screw rod part threadedly connected with the adjustable nut 4. The adjustable nut 4 abuts against the lower end of the hole aligning device 1. Before installing the hole aligning device 1, the adjustable nut 4 is adjusted according to the specifications of the flower plate 7 and the injection pipe 8, and the adjustable nut 4 is always attached to the lower end of the hole aligning device 1. The injection hole aligning device 2 is a conical body coaxially installed on the upper end of the extension guide column 3, and the diameter of the injection hole aligning device 2 gradually increases from top to bottom, which is convenient for inserting into the injection hole 801 and ensuring the horizontal placement of the injection pipe 8. When adjusting the adjustable nut 4, the distance between the injection hole aligning device 2 and the hole aligning device 1 is accurately controlled, and then the distance between the injection hole 801 and the hole 701 of the flower plate is controlled. The compressible spring 5 is sleeved outside the extension guide column 3, and the two ends of the compressible spring 5 abut against the hole aligning device 1 and the injection hole aligning device 2 respectively. In combination with the compressible spring 5 whose spring force is greater than the gravity of the injection pipe, when the injection pipe 8 is installed on the two injection hole aligning devices 2, the distance between the injection hole 801 and the hole 701 of the flower plate is prevented from changing.

[0023] In use, this utility model first adjusts the adjustable nut 4 according to the specifications of the tube sheet 7 and the blow pipe 8, and then adjusts the distance between the blow hole alignment device 2 and the tube sheet hole alignment device 1. This allows for precise positioning of the distance between the blow hole 801 and the tube sheet hole 701, adapting to the positioning and installation requirements of most filter elements on the market. After adjustment, the two tube sheet hole alignment devices 1 are placed inside the tube sheet hole 701, and the hollow truncated cone structure of the tube sheet hole alignment device 1 ensures that the tube sheet hole alignment device 1... Quickly adjust to a horizontal position, then align the two nozzles 801 of the blowpipe 8 with the two nozzle alignment device 2 and place it. The conical structure of the nozzle alignment device 2 ensures that the blowpipe 8 is horizontal, thus enabling the blowpipe 8 to be quickly installed above the tube sheet 7. The spring force of the compressible spring 5 is greater than the weight of the blowpipe, which ensures that the distance between the nozzles 801 and the tube sheet holes 701 will not change during the installation of the blowpipe 8. When adjustment is needed, the adjustable nut 4 can be easily adjusted below the tube sheet hole alignment device 1, making the operation easier.

[0024] As a preferred embodiment of this example, it should be further explained that a level 6 is installed on the upper end of the orifice alignment device 1. The level 6 can accurately determine whether the upper surface of the orifice alignment device 1 is horizontal. More preferably, a level 6 is installed on the upper end of the orifice alignment device 1 on both sides of the telescopic guide post 3. The two levels 6 are perpendicular to each other in the horizontal direction. By combining the two levels 6, it is possible to more accurately determine whether the upper surface of the orifice alignment device 1 is horizontal.

[0025] As a preferred embodiment of this invention, it should be further explained that four levels 6 are evenly distributed on the upper end of the alignment device 1 around the flower plate holes of the telescopic guide post 3. The four levels 6 can correct each other to avoid problems with one level 6.

[0026] As a preferred embodiment of this invention, it should be further noted that the level 6 is a cylindrical level, which is existing technology and can be directly purchased from the market. It is also very convenient to install.

[0027] As a preferred embodiment of this invention, it should be further explained that the diameter of the screw part is smaller than the inner diameter of the vertical center hole. When the telescopic guide post 3 is installed on the orifice alignment device 1, it will not damage the smoothness of the vertical center hole in the middle of the orifice alignment device 1, thereby ensuring the precise fit between the vertical center hole and the middle of the telescopic guide post 3, and ensuring that the telescopic guide post 3 is in a vertical setting state.

[0028] It should be explained finally: above described only is preferred embodiment of the utility model, and is not for limiting the protection scope of the utility model. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be contained in the protection scope of the utility model.
